As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Clever jays switch food-finding tactics

Jays demonstrate "flexible tactics" by switching between storing food and stealing from others' stashes, scientists have found.

The woodland birds are known as the shy members of the notoriously intelligent corvid family.

But birds were observed boldly stealing food from subordinates' hiding places in the University of Cambridge study.

Researchers found that the jays' strategy was dependent on the relative social rank of their opponent.

The results are published in the journal Animal Behaviour.

Eurasian jays live in woodlands and feed primarily on acorns. Past studies by the University of Cambridge team have highlighted the birds' remarkable ability to plan for the future by storing thousands of the nuts and returning to them later.
